Very tedious trilogy. It had great potential but just drowned the reader in unnecessary detail on subjects that had nothing to do with the theme of the books(s).
As the subject matter is very interesting to me, I started the series with great expectations and positive anticipation. I ended up very disappointed.
That wealth of detail was the best part for me. If one wants to be immersed in such a world/scenario, then it is a pleasure. It's much the same as savoring the paeans to nature in the Lord of the Rings trilogy books. There's more to some books than the plot and characterizations.
